Bayer Makrolon Polycarbonate Flat Sheet offer high impact strength

Makrolon Polycarbonate products have a great blend of helpful features which include temperature resistance, impact resistance and optical properties position polycarbonates in between commodity plastics and engineering materials.
Polycarbonate is definitely a tough material. Even though it features outstanding impact-resistance, it possesses reduced scratch-resistance and so a hard coating typically is applied to polycarbonate eye wear lenses as well as polycarbonate exterior automobile equipment. The characteristics associated with polycarbonate are like those of common Acrylic materials, and yet polycarbonate is going to be stronger, it is usable in a wider temperature range and is a bit more expensive. This plastic polymer is highly transparent to visible light and it has better light transmission characteristics than most grades of glass.
Polycarbonate has a glass transition temperature of approximately 150 °C (302 °F), consequently it softens slowly above this point and flows above about 300°C (572 °F). Tools need to be held at higher temperatures, generally above 80 °C (176 °F) for making strain- and almost stress free products.
Unlike many thermoplastics, polycarbonate can undergo dramatic shape changes without cracking or breaking. Subsequently, it is sometimes processed and formed   without needing to be heated using standard sheet metal techniques, such as forming bends with a brake. For even sharp angle bends having a tight radius, no heating is generally necessary. This makes it useful for prototyping applications where transparent or electrically non-conductive parts are required, which can't be created from sheet metal. Remember that PMMA/Plexiglas, that is similar in looks to polycarbonate, but is brittle and cannot be bent without heating.

The light weight of polycarbonate, as opposed to glass, has led to development of electronic touch screens that replace glass with polycarbonate, for use in mobile and portable devices. Such displays include newer e-ink and several LCD screens, though CRT, plasma screen and other LCD technologies which still require glass for its higher melting temperature and its ability to be etched with finer detail.
Other types of items made from Polycarbonate include durable, lightweight luggage, MP3/digital audio player cases, computer cases, riot shields, instrument panels, and common style blender jars. Many toys and hobby products are made of polycarbonate parts, e.g. fins, gyro mounts, and flybar locks for use with radio-controlled helicopters.
For use in applications exposed to weathering or UV-radiation, a special surface treatment is needed. This can be a coating (e.g. for improved abrasion resistance), or as a coextrusion for enhanced weathering resistance.
The Makrolon Polycarbonate is a thermoplastic that at the beginning, starts as a solid plastic material in the form of small pellets. In a manufacturing process called injection molding, the pelletized resin is heated until they melt in to a thick liquid. The liquid polycarbonate is then rapidly injected into molds, compressed under high pressure and cooled to form a finished product in a matter of minutes.
